  The stressful school life and unhealthy lifestyles cause some problems to students.Here are some key mistakes and some tips.

  ■Sitting too long

  So much homework and many computer games make students sit for several hours without standing or walking around.Because of long time sitting,some students have got diabetes (糖尿病) and heart disease(疾病).

  Tips:●Get up and out of your chair for about five minutes every hour.

  ●Walk over to a person instead of sending e-mails or text messages.

  ■Eating irregularly

  Some students develop unhealthy eating habits.Fast food becomes more often.Heavy studying and stress prevent students from eating meals regularly.

  Tips:●Eat breakfast with eggs at the start of every day.

  ●Buy healthy snacks like nuts and fruit,and eat them between meals.

  ●Have three meals a day at the right time.

  ■Sleeping less

  Not enough sleep breaks the smooth cycle of our biological clock(生物钟).It can cause heart disease and high blood pressure(高血压).

  Tips:●Be sure to sleep for seven to eight hours every night.

  ●Have a rest for about 30 minutes at noon.

  ■Having lots of energy drinks

  An energy drink or an extra cup of coffee might seem like the only way to get through a late-night study time.High levels of caffeine(咖啡因) can also cause high blood pressure.

  Tips:●The safest way to get more energy is to eat regular meals,sleep well,exercise and drink lots of water.

  You are probably familiar with the saying:An apple a day keeps the doctor away.A recent research carried out by the Chinese University of Hong Kong may change the saying:

  An apple a day may keep aging away.

  The research chose fruit flies(果蝇), as they share many genes(基因)with humans.The fruit flies were either fed normally or had an apple extract(浓缩物) added to their diet.

  It turned out that those fruit flies that were given apple extract lived about 55 days-five days longer than the flies that were normally fed.The research group also found it easier for the flies to walk,climb and move about as they aged.

  According to the result, the researchers believed that the antioxidants(抗氧化剂) in the apple extract helped clean up dangerous chemicals(化学物质) that cause illnesses,as well as aging.

  In another study,researchers examined diets of thousands of women.They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke.

  The apples' genetic code(遗传密码) was discovered recently.It allows scientists to develop nicer and healthier fruits.Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer.

  Apples that kill the desire(欲望) to eat could also be produced, with the first“extra-healthy''apples on supermarket shelves within just four or five years.

  The team that keeps studying apple DNA includes 100 scientists from five countries.Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant,which would finally become today's apple tree, experienced a great genetic change.The number of many of its genes doubled.The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches,strawberries and other related fruits.

(1)

Why were fruit flies used for the research?

[  ]

A.

Because they have a similar diet to humans.

B.

Because they have a history as long as apples.

C.

Because they share a lot of genes with humans.

D.

Because they feed on nothing but apple extract.

(2)

What result did the researchers find out?

[  ]

A.

Apples produce chemicals that can change human genes.

B.

Apples have antioxidants that kill chemicals that cause aging.

C.

Apples are rich in vitamins that are needed in humans'bodies.

D.

Apples produce chemicals that make apples taste more delicious.

(3)

What happened to apples around 65 million years ago according to the research?

[  ]

A.

Their genes stopped their development as the environment got worse.

B.

Their genes became twice in number but they finally died off like dinosaurs.

C.

They experienced a great genetic change making them used to worse conditions.

D.

They went through a similar development to peaches, strawberries and other related fruits.

(4)

What can we infer(推断)from the passage?

[  ]

A.

Eating apples may bring us more advantages than we might believe before.

B.

People who have the habit of eating apples don't need to see a doctor.

C.

Apples that kill the desire to eat are already available in supermarkets now.

D.

People will eat apples instead of peaches and strawberries from now on.

阅读下面短文,选出可以完成句子或回答所提问题的最佳选项。

  Two old men shared a room on the fourth floor of an old people's home in the city centre.

  Both men were very old and very ill, and they spent 24 hours a day in bed in the room.

  Fortunately (幸运地), one of the old men had his bed by the window, and every day he spent hours telling his friend on the other side of the room what he could see through the window.

  He told him about the traffic going by, the children playing in the park opposite, and the birds flying in the trees.

  The old man by the inside wall got a lot of pleasure from hearing about the world outside, but after a time he began to get rather jealous (嫉妒).

  How nice it would be, he thought, if he had the bed by the window and could see everything for himself, instead of just hearing about it.

  One night, the man by the window called to his friend, “Quick! Pull the alarm by your bedI don't think I'm going to last the night!”

  But his friend, imagining an empty bed over by the window, did nothinghe just closed his eyes and went back to sleep.

  Sure enough, the next morning, the nurse found the man dead in his bed by the window.

  The old man was very excited as they moved him into the empty bed by the window. He sat up in bed, pulled back the curtain (窗帘), looked outand saw a blank brick wall.

1.Where did the two old men live?

[  ]

A.In their own house.

B.In an old people's home.

C.In the hospital.

D.It is not clear.

2.What did the old man by the window see?

[  ]

A.The traffic going by.

B.The children playing in the park opposite.

C.The bird flying in the trees.

D.Nothing except a blank brick wall.

3.Do you think the other old man believed what the man said?

[  ]

A.Yes.
